(Portland, OR) -- Students at schools across Portland plan a walkout today over their demand for climate action by the city. Students with the group called Portland Youth climate Strike organized a similar action last fall in which they say about two-thousand students took part in a walkout. Portland school officials have sent letters home to parents asking them to discuss the strike with their kids and to make plans to keep them safe if they do walk out. Students plan to meet at City Hall at eleven o-clock and march to Revolution Hall to participate in the Portland Climate Festival.
